Being in SoCal and having an affinity for local & indigenous species, I developed an interest what I think is the Coastal Live Oak

I'm talking about the plentiful, big (30'+), acorn-dumping, fat trunked sprawlers that get as wide as they do tall, pretty sure it's the
Quercus agrifolia. I have one, prob 4 or 5 years old- 2 years in pot, that I just put in a 6" deep-8" diam., red clay pot (cottaterra?) from a deeper clay pot.
I'd just like any tips on how to keep it alive & make it thrive. Do these great oaks need anything special, real different from other trees?
I read they like it moist, but I thought they liked it drier?
I haven't developed any soils yet, I still use potting soil & clay conditioner mix for all, what do these oaks like for food? What kind of fertilizers do I use? Acidy soil?
Right now, the leaves seem real hard. I prob should have left it in the deeper pot (I want it to grow) but it seemed to have a bunch of feeder roots & be ready to move.
I see there is also smaller, scrubbier versions (
dumosa or others), how do I tell?
Are these
Quercus related to what people think of as "Oak Trees" the red oaks, white oak, etc?
Any tips pertaining to these trees would be cool.
Thanx.
I have no clue on containers but I guess that's another section.
